1 like165 views
This document describes a dual-axis solar tracking system developed using Arduino that aims to maximize solar energy collection. It discusses how solar trackers can improve power gain by rotating panels to always face the sun's position. A dual-axis tracker is able to rotate in both horizontal and vertical directions, unlike single-axis trackers. The proposed system uses Arduino, light dependent resistors, motors, and a display to control panel rotation based on sun position. Experimental results show the dual-axis system improves efficiency by 30-45% compared to fixed and single-axis mounting.

Abstract - The world is now moving towards therenewable
energy source due to various factors like pollution and cost of
non-renewable energy sources. One of the major renewable
energy sources is Sun. In this paper Arduino based Dual-axis
solar tracking system proposed in order toget maximumsolar
energy. The Arduino is used to give command to rotate the
solar panel. Solar trackers are used to improve thepowergain
from solar energy. Solar power is changes due to the seasonal
variation and tilting of earth which changesthepositionof the
sun in the sky. In this regard dual axis solar tracking is
practically implemented and performance is compared with
fixed mount and single axis solar tracking system. Finally,
experimental result clearly evident that proposed method
gives better efficiency compared to fixed mountandsingleaxis
solar tracking system.

1. INTRODUCTION
Solar energy is emerged as a possible source of renewable
energy over the past two to three decades. This solar energy
is converted into electrical energy by using solar panel
according to the principle of photovoltaic effect. Out of
various renewable energy sources solar energy is widely
used. Because it is simple and it is easy to use in household
too. Solar Trackers is a device used for the rotation of solar
panel according to the sun’s rays. To utilize this renewable
solar energy solar trackers are employed [1]. Forstaticsolar
panel, there is no movement in the panel. But the position of
the sun changes during rising and setting (sun rises in the
east and sets in the west). Due to this reason, single axis
solar tracker is developed for rotation of solar panel in east
and west direction. But due to the rotation and revolution of
earth we cannot get equal amount of sunraysthroughoutthe
year. So that we adopted dual axis solar tracker to utilize the
solar energy effectively and efficiently by rotating the panel
in both horizontal and vertical direction. The main objective
of dual axis solar tracker is to increase the efficiency of the
solar panel by 30-45% when compared to the static and
single axis solar tracker. The literature survey clearly shows
the different methods of solar tracking for maximum
utilization of solar power [1-15].
The single axis tracker is able to rotate only on horizontal
(or) vertical. But this dual axis tracker is able to rotate on
both horizontal and vertical movement. This dual axis solar
tracker was implemented by using Arduino board [2]. Low
cost of implementation by Arduino is the reason behind
choosing Arduino in this project [3]. This was achieved even
by using microcontroller [4].
Figure.1 Mechanism of dual axis tracker
The above figure.1 shows the basic operating mechanism of
dual axis solar tracker. It is basically an Azimuth-Altitude
dual axis solar tracker [5]. Altitude refers to elevation of
angle between a substance and the observer’s location. It is
basically between the angles of 0-90◦. Zenith distance can
also be used instead of altitude. Then azimuth is usually
analysed from north and increasing towards east [6]. This is
mainly employed to get the maximum efficiency when
compared to the static and single-axis solar tracking system
[7]. To achieve this, we used Arduino UNO, LDRs, DC motor,
LCD and solar panel. In [8] automatic solar trackingandtwo
axis solar tracking is proposed in [9] forbettersolartracking
based on the position of sun.
The main contribution of proposed paper is given below:
•To trace more solar power in different location in different
time period in a day to get maximum efficiency.
•To develop the Arduino based Dual axis solar tracker.
•To compare the efficiency of dual axis tracker with single
axis tracker.
2. DUAL AXIS SOLAR TRACKER
The block diagram of our dual axis solar tracker system is
shown in Figure.2. It consists of an Arduino board, LDR, LCD
display, DC motor. An input command is given totheArduino
board. Four LDRs are connected to the light comparison unit
[14]. This unit gives signal to the Arduino. The Arduino in
turn command the motor driving circuit to rotate the solar
panel in horizontal or vertical position.](https://image.slidesharecdn.com/irjet-v6i3188-190814062657/85/IRJET-Dual-Axis-Solar-Tracking-System-using-Arduino-1-320.jpg){kind=tracking}

3. WORKING
In this system, four LDRs are fixed to sense the intensity of
light (Two for Azimuth position sensor and another two for
Altitudeposition sensor). The analog signal from the sensors
is given to the in-built ADC (Analog to Digital Converter) and
light comparison unit. This output is given as an input to the
Arduino board along with the input command. The output of
the Arduino is given to the motor driving circuit. Two DC
motors are connected with thedrivingcircuit,oneforvertical
and another one forhorizontal movement.Themotorrotates
the solar panel perpendicular to the position of sun’s rays.
Then finally the output power is displayed in the LCD. In this
project, LDR combination plays an important role. The
combination of signals is fed to the Arduino and this bit
pattern is shown in table 1.
Table.1 Desired Bit Pattern
LDR 1 LDR 2 LDR 3 LDR 4
1 1 0 0
0 1 1 0
0 0 1 1
1 0 0 1
When the motor gets the last bit pattern in the table 1, the
motor will move the panel to its initial position and again
follow these steps, when sun starts rising in the next day.
Even a load is taken from the solar panel by connecting the
panel with battery and inverter. The battery is used to store
and give the DC supply to the inverter, which is taken from
the solar panel. Then the output DC supply was given to the
inverter which converts DC to AC. Then a load is connected
along with it. This function is represented in the Figure.3
which is shown below.

3.1 Solar panel
The solar panel works based on the principle of photovoltaic
effect which converts the solar energy into electrical energy
[10]. There are various types of panels are available like
monocrystalline, polycrystalline, amorphous, and hybrid. In
this project we use 40W 12V amorphous solar panel is
considered.
Figure.4. Amorphous solar panel
The Amorphous solar panel was shown in above Figure.4.
The cost and silicon requirement of amorphous panel is low
when compared with the other types of solar panel.
3.2 Arduino
In our project, we proposed Arduino based dual axis solar
tracker [11]. Arduino board unit controls the movement of
solar panel that rotates and traces the direction of sun [12].
Arduino board uses variety of microcontrollers and
controllers. It is equipped with both analog and digital
input/output. It has 14 digital input/output pins (of which
six is used as PWM output), six analog inputs, a 16 MHz
crystal oscillator, a USB connection, a power jack and a reset
button is used. The input command wasgiventotheArduino
using Integrated Development Environment platform. The
Arduino Uno differs from all preceding boards because it
does not use the FTDI USB-to-serial driver chip. Instead, it
features the ATmega8U2 programmed as a USB-to-serial
converter.

table.3. As a result, it creates a solution for effective
utilization of solar energy and thus helps in creating smart
houses.

efficiency of solar panel. The proposed dual axis solar
tracker is more effective than the existing single axis solar
tracker and fixed mount. The proposed solar tracker which

effectively improved.
